SPECIFICATION forming part of Letters Patent No. 696,700, dated April 1, 1902.

Application tiled July 5,1901. Serial Nm 67,241. (No modell) To cti/ whom, t may con/cern:

Be it known that I, FREDERICK TILLMANY, a citizen of Germany, residing at San Francisco, in the county of San Francisco and State of Calfornia,have invented cert-ain new and useful Improvements in Vehicle-Tires; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to that class of devices known in the art as vehicle-tires g and it has for its objects to provide a tire having the requisites of lightness, strength, resiliency, and durability and one in which the first cost is comparatively small.

I dispense with the ordinary pneumatic tire and the disadvantages incident to the use `thereof and provide a mechanically-elastic metal tire capableof being quickly and readily positioned on or removed from the grooved rim of the Wheel.

Other objects and advantages of the invention will appear to those familiar with this class of devices as, the following specification is gone over.

I have clearly illustrated the invention in the accompanying drawings, and in the several views shown have employed'like letters of reference to indicate like parts, and in Which- Figure l is a side elevation of the complete tire, showing its abutting ends detached from each other and removed from the rim of the Wheel. Fig. 2 is a cross-section taken on the line :t :c of Fig. l. Fig. 8 is' a longitudinal section of the tire, taken through the abutting ends and in the direction'cf the line y y uniting the abutting ends of this tube A Without interrupting the smooth outer contour of the tire.

One extremity C of the tube A is contracted in diameter an amount equal to the thickness of the material, which contraction will permit the opposite female end D of the tube to slip over this Inale portion C and form a smooth outer surface, as shown in Fig. 3. New in order to lock these ends of the tube A. together, and thereby prevent their springing apart, I have provided the spring E, which is securely fastened to the interior of one end of the tube A. The opposite end of the tube is provided With a perforation F, which is adapted to receive and engage the knob ct on the free extremity of the spring E.

From the construction so far gone into it will be seen that the positioning of the tire on the rim is accomplished by simply springing the tube over the rim and then forcing the tivo ends of the former together until the knob a engages the perforation F. Bysim ply pressing inward the knob d, Which is reached through a small hole in rim B, the ends of the tire Will spring apart ready for removal from the rim. Now in order to provide a durable non-slipping tractional surface for the tire I have caused a portion G of the periphery thereof to be depressed, as shown in Fig. 2, while the space between this portion G and the outer line of the tire I occupy bya tightly-secured strip of compressed leather H.

It will be readily seen from the foregoing description that I have provided a very simple and effective tire which is light, durable, and comparatively inexpensive and which is particularly applicable for use ou bicycles, automobiles, and all other light-running vehicles.

I am aware that changes in the form and proportion of parts of the devices herein shown and described as an embodiment of my invention can be made Without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes and alterations as fairly fall Within the scope of my invention.

I-Iaving thus fully described my invention,

what I claim, and desire to secure by Letters i extending the entire length of said tire, and Patent, ism 'a compressed-leather strip secured in said l. A Vehicle-tire or the like consisting of t depressed portion and forming a non-slipping I5 single metal tube formed with a male and ai I traetional surface for said tire, substantially female end, a spring at one end of said tube as and for the purpose set forth. and a depression in the opposite end, said In testimony whereof I affix my signature spring being adapted to engage said depresin presence of two Witnesses. sion and hold said ends together, for the nr- T pose Set forth n C p y FREDERICK TILLMANI 2.
